How the Armory Pass turns playtime into credits
The Armory runs on a simple conversion: match XP becomes Armory Credits at a rate of about 300 XP per credit. A single Armory Pass caps at 40 credits, and you can hold up to 5 passes at once, so a full run banks up to 200 credits before you have to spend. In practice each pass is roughly 25–30 hours of play to fill, which is exactly the grind a boost removes — the value here is the raw playtime, not any rank. That concrete cadence is what the calculator prices against: you choose how many credits you need and it quotes the XP grind to get there.
